Merge branch 'master' of https://github.com/react-native-community/react-native-webview into pr/296

README.md

 
 - [x] iOS (both UIWebView and WKWebView)
 - [x] Android
-- [ ] Windows 10 (coming soon)
 
 _Note: React Native WebView is not currently supported by Expo unless you "eject"._
 
       <WebView
         source={{ uri: "https://infinite.red/react-native" }}
         style={{ marginTop: 20 }}
-        onLoadProgress={e => console.log(e.nativeEvent.progress)}
       />
     );
   }
 
 - If you're getting `Invariant Violation: Native component for "RNCWKWebView does not exist"` it likely means you forgot to run `react-native link` or there was some error with the linking process
 
-### Contributor Notes
+## Contributing
 
-- I've removed all PropTypes for now. Instead, we'll be using Flow types. TypeScript types will be added at a later date.
-- UIWebView is not tested fully and you will encounter some yellow warning boxes. Since it is deprecated, we don't intend to put a lot of time into supporting it, but feel free to submit PRs if you have a special use case. Note that you will need to specify `useWebKit={false}` to use UIWebView
-- After pulling this repo and installing all dependencies, you can run flow on iOS and Android-specific files using the commands:
-  - `yarn test:ios:flow` for iOS
-  - `yarn test:android:flow` for Android
-- If you want to add another React Native platform to this repository, you will need to create another `.flowconfig` for it. If your platform is `example`, copy the main flowconfig and rename it to `.flowconfig.example`. Then edit the config to ignore other platforms, and add `.*/*[.]example.js` to the ignore lists of the other platforms. Then add an entry to `package.json` like this:
-  - `"test:example:flow": "flow check --flowconfig-name .flowconfig.example"`
-- Currently you need to install React Native 0.57 to be able to test these types - `flow check` will not pass against 0.56.
